Title: Identification of failed fuel elements
IPC: G21C3/17
Filed: 1975-09-25
Abstract: 1475245 Identification of defective fuel assemblies UNITED STATES ENERGY RESEARCH & DEVELOPMENT ADMINISTRATION 25 Sept 1975 [15 Oct 1974] 39218/75 Heading G6C A fission product gas trap provided in the upper portion of each fuel assembly in a liquidmetal-cooled nuclear reactor consists of an inverted funnel 21 of less diameter than the fuel assembly 11 and having a normally closed valve 22 at its apex. An actuating rod 23 extends upwardly from the valve 22 through an adapter 25 to a point where it can be contacted by the fuel handling mechanism 19 for the reactor. Any fission gases released in the fuel assembly 11 will rise in the assembly and some will be trapped in the funnel 21, the remainder rising to the reactor cover gas to indicate the presence of defective fuel assembly. The gripper mechanism 19 is then lowered on to the adapter 25 of each of the fuel assemblies in turn, whereupon an orientation blade 30 enters a locating slot 26 and pushes downwardly against the action of a spring 28 on actuating rod 23. The valve 22 is thereby opened and any bubble of fission gas present in the funnel 21 is released, as shown in Fig. 4. Conventional monitoring equipment is used to detect the increase in radioactivity in the cover gas caused by release of the bubble.

Title: Improvements in pneumatic driers
IPC: D21F3/10
Filed: 1959-02-17
Abstract: 919,632. Drying apparatus. MARK, A. Feb. 17, 1959 [Feb. 20, 1958], No. 39474/62. Divided out of 919,631. Class 34 (2). In a pneumatic drier of the kind comprising one or more tubular vertical drying chambers inserted in a drying conduit to receive a gas stream carrying in the suspended state a divided material to be dried, the or each chamber having a lower axial inlet and an upper axial outlet, additional fresh hot drying gas is admitted tangentially into the or at least one of the said chambers at a point situated at a vertical distance from the said inlet at least equal to half the inner height of the chamber. The drier shown comprises drying chambers 28, 29, Fig. 3, of bi-conical shape disposed in vertical succession, the maximum diameter of the upper chamber being larger than that of the lower one. Moist material is fed into the chamber 28 in front of a jet of hot air issuing from a nozzle 4 from a hopper 13a through a screw-feeder 11, 12a. In the upper portion of each chamber additional fresh air from the generator 2 is introduced tangentially through inlets 10<SP>1</SP>, 10<SP>11</SP> such that the heaviest particles in the said portion are centrifugal against the conical wall thereof and tend to roll downwardly thereby increasing their time in the chamber. Balls 27 in the upper chamber 29 are " fluidized " by the rising air and thus form a vibrating screen preventing the heaviest particles rising directly into the upper portion of the chamber 29 without previously whirling in the lower portion thereof. The air stream is drawn through the drier by an exhaust blower 8 partial recirculation of the air occurring through a pipe 30 which connects the outlet of the blower with a nozzle 31 disposed coaxially in the nozzle 4. A blower may be provided between the generator 2 and the pipe 10. In the latter case the recirculating pipe and nozzle 31, 30 may be dispensed with. A further embodiment is described with reference to Figs. 1 and 2 (not shown) which is identical with that described in Specification 919,631.

Title: Brick handling systems
IPC: B65G67/14
Filed: 1974-09-13
Abstract: 1486307 Brick handling apparatus A M I INDUSTRIES Inc 13 Sept 1974 [15 Oct 1973] 40027/74 Heading B8C A brick handling apparatus comprises a gripper transfer assembly 33 for unloading a kiln car 10 and depositing first and second groups of bricks, such as 62, 63, 64, on a support table 36 on opposite sides 61, 67 of a delivery conveyer 51, and a transfer plate 53 for pushing ranks and files of bricks on to the delivery conveyer 51 from both sides 61, 67 of the support table 36. The gripper transfer assembly 33 comprises a secondary carriage (37) Fig. 2 (not shown) which is supported on a main carriage 34 and carries a vertically movable column (38) Fig. 2 (not shown) having at its lower end a support plate (39) Fig. 2 (not shown) on which a pair of opposed gripper plates (41, 42) Fig. 2 (not shown) is mounted. The support plate (39) can be rotated through 90 degrees to permit the gripper plates (41, 42) to grip rows of bricks extending either lengthwise or laterally on the kiln car 10. Even movement of the gripper plates (41, 42) relative to one another is ensured by rack and pinion arrangements (46) Fig. 2 (not shown) extending between the plates (41, 42). The upper run of the delivery conveyer 51 passes through a recess in the support table 36 which is movable in directions transversely of the delivery conveyer so that edges 71, 77 of the recess can be positioned to overlie the delivery conveyer 51. The transfer plate 53 is pivotally mounted so that it can be moved along a frame 47 and over a retainer plate 52 with which it co-operates in a downwardly extending position to transfer ranks, i.e. rows extending transversely of the delivery conveyer 51, containing a predetermined number of bricks on to the conveyer 51. The retainer plate 52 is also movable along the frame 47. The delivery conveyer 51 moves the bricks to a retainer gate 56 beyond which they are supplied to a stacking apparatus 57.

Title: Photographic Cameras
Inventor: STEISSLINGER KURT
IPC: G03B17/30
Filed: 1967-09-01
Abstract: 1,197,994. Cameras. EASTMAN KODAK CO. Sept. 1, 1967 [Sept. 1, 1966], No.40106/67. Heading G2A. A photographic camera includes a chamber for a take-up spool around which the exposed film is wound such that the leading end of the film lies between subsequent portions of the film, guide means for directing the film to the take-up spool, and means for deflecting the leading end during rewinding to prevent it from being withdrawn from the chamber in contact with either of the said portions. As shown in Fig. 6, the film is being unwound from the spool 7. The spool is loaded by feeding the leading end 3a of the film 3 through a slot 7b in the spool 7, closing the camera back 1, which causes the leading 3a to fold back over the spool 7 and part of the subsequent film 3, and winding the spool 7 such that the leading end 3a is held between subsequent portions of the film 3. The film 3 passes over a guide surface 6 and between a nose 6b on the guide surface 6 and a roller 13 mounted on the camera back 1. On rewinding the roller 13 the nose 6b acts to prevent the leading end 3a from being withdrawn with the overlying film and the roller 13 prevents it being withdrawn with the underlying film as shown in chain-dotted lines. In another modification, Fig. 7, (not shown) the nose 6b is absent, and a channel is located beneath the guide 6 and into which the leading end 3a will project as it becomes free during the rewinding. A light sealing strip may extend along the camera back hinge 5 to prevent light entering and to prevent the leading end 3a catching in the opening. Alternatively the camera back may be hinged at the end receiving the cassette of unexposed film, Fig. 9 (not shown), and a spring on the camera back positions the cassette with respect to the guiding path. Specifications 1, 123, 402 and 1, 123, 403 are referred to.

Title: Improvements relating to couplings between waveguides
IPC: H01P5/08
Filed: 1958-12-12
Abstract: 870,873. Radar; aerials. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Dec. 12, 1958 [Dec. 12, 1957], No. 40191/58. Class 40(7) [Also in Group XL(b) ] A radar or antenna-coupling system includes a junction 11 (see Group XL(b) ) coupling a circular waveguide 1 to a pair of rectangular waveguides, 2, 3 whose axes are arranged at right angles. The distribution of energy between the guides 2, 3 depends upon the polarization of the wave propagated in the circular guide 1. Thus, if the guide 1 is connected via a rotatable section 23 to a coaxial-line feeder 21, the orientation of section 23 determines the distribution of energy between two antannae connected respectively to guides 2, 3. The radar system of Fig. 4 comprises two junctions 11, 24, the circular branches of the junctions being aligned and coupled together through a ferrite rotator 27. When the rotation is zero guide 3 is coupled to guide 26 and guide 2 to guide 25. A rotation of 90 degrees commutates these couplings. Thus, if guide 26 is connected to a dissipative termination, signals from guides 2 and 3 may be applied in rapid alternation to guide 25 which may feed the I.F. section of a radar receiver. The two signals may respectively be echo pulses and reference pulses, the latter being used to regulate the gain of the receiver. Alternatively, sum and difference echo signals may be fed alternately to the same amplifier. In the radar system of Fig. 5, energy from transmitter 35 is divided at junction 34 into equal parts and fed to junction 11 through guides 2, 3. The polarization of the wave in the circular output guide 29 is determined by an adjustable 0 to 360 degree phase-changer 40 in the guide 3. Received energy is distributed between receivers 36, 37, the amplitude distribution being used to determine the polarization of the signal. In a modification (Fig. 6, not shown), the whole input energy is applied to the guide 2 and the polarization of the transmitted signal is regulated by a phase-shifter in the circular waveguide 29.

Title: Photochromic and photoconductive constructions and their use in imaging processes
IPC: G03G5/06
Filed: 1968-08-23
Abstract: 1,244,021. Tenesbrescent materials and uses thereof. MINNESOTA MINING & MFG. CO. 23 Aug., 1968 [25 Aug., 1967], No. 4O522/68. Heading C4S. [Also in Divisions G1 and H1] A semi-conductive layer which is both photoconductive and photochromic comprises at least one 1 - carboxamidoanthraquinone (specific examples disclosed) in which the nitrogen atom is directly bonded to the nucleus and has a hydrogen atom directly bonded thereto and at least an equimolar quantity of at least one amine having a pK b  value not greater than that of benzylamine. Further the anthraquinone and amine together have an electron spin resonance value of at least one when measured in an inert solvent at a 0 01 molar concentration, and provide a minimum ratio of light conductivity to dark conductivity of 50. In the examples a photochromic member is made using a compound of formula which is both a carboxamido-anthraquinone and an amine. The layer may be self-supporting or deposited on to a substrate of aluminized polyester sheet either as a powder or dispersed in copoly(vinyl alcohol - vinyl acetate - vinyl butyral), copoly styrene - butadiene or chloroform. Potassium bromide may be added to form colour centres or eosin or erythrosin used as sensitizers. Irradiation of the layer generates stable free radicals and changes the colour of the layer. The colour change is reversed by the presence of paramagnetic compounds such as O 2 , N 2 0 or Cu<SP>2</SP>+. In use the layer is normally protected by a layer of polyvinyl alcohol which is stripped away to erase the image pattern formed. The layer is sensitive to an electron beam. Applications include electron beam recording layers imaging layers, sunglasses, light modulation, light filtration and for monitoring oxygen leakage in vacuum devices containing special foods and medecines for example, the magnitude of the colour change in the latter instance being a measure of light and also oxygen available. In an imaging device, for example, the compound may be mixed with a styrene/butadiene copolymer and coated on the polyester side of an Al coated polyester sheet and a p.v.a. film coated thereon until erasure of a black image produced by illumination through a negative or by an electron beam was required, when removal of the p.v.a. layer effected reversal to the original state. In an embodiment using acrylate resin latex top coat, the restoration was a function of its oxygen permeability. Alternatively, after use in a thermographic copying process, the image produced in the original sheet by light exposure, may be removed by heating.

Filed: 1961-11-15
Abstract: 993,020. Sterilizing canned evaporated milk. FMC CORPORATION. Nov. 15, 1961 [Nov. 17, 1960], No. 40820/61. Heading A2D. In a process for sterilizing canned evaporated milk to a desired Fo sterility value of 4.7, each can of milk is preheated to a temperature of substantially 212F., the milk is then partially sterilized to less than half the desired sterility value and then fully sterilized to the desired sterility value. Throughout the process, the temperature of the cans never exceeds that of the milk by more than 35F., to prevent burn-on. Cans of evaporated milk 10, e.g. at a temperature of 50F., are passed through zones of a preheating water-bath 11, in which zones the water temperature gradually increases from 120 to 212F. Each can is in the water-bath for 6 to 8, preferably 7, minutes and the milk therein attains, for example, a temperature of 210F. The preheated cans 12 are then passed through a sterilizer 13 containing pressurized steam at a temperature between 235 and 245F., e.g. 240F. Each can is in the sterilizer 13 for 2.35 minutes, so that the milk attains a temperature between 233 and 243F., e.g. 238F., and a Fo sterility value of, for example, 0.8. The partially sterilized cans of milk 14 are then passed through a second sterilizer 15 containing pressurized steam at a temperature between 260 and 264F. Each can is in the second sterilizer for 2.35 minutes, so that the milk attains a temperature between 258 and 262F. and the desired Fo value of 4.7. Finally, the sterilized cans of milk 16 are passed through a cooling bath 17 containing water at a temperature between 120 and 70F., each can being in this bath for 7.5 minutes, so that the temperature of the finally sterilized canned milk 18 is reduced to room temperature, e.g. 100 F. References to publications, which explain the meaning of Fo sterility value, are given in the Specification.

Water is heated and evaporated, and the vapour is superheated, in a single pass in one direction through channels in a reactor. Feed water enters through ring 13, flows down outside a partition 9, and rises through fuel channels 3, forming superheated steam which collects in dome 5; some water rises outside channels 3 to act as a moderator and mixes with the feed water; alternatively the moderator may be a separate mass of D 2 O in a tank. The pressure in dome 15 forces water through the fuel channels; the saturated steam in this dome is produced by heat lost from dome 5. The coolant channels are made very narrow so that moderation is provided almost entirely by the water surrounding them, which does not boil; the channels can thus be flooded in safety, for cleaning, soiling of the channels being indicated by a rise in steam temperature. The channels are fixed at the top to a perforated plate 4 and can be removed with it but are free to expand at the bottom. The saturated steam pressure, superheated steam temperature, and water level are kept constant and the controlrods are adjusted in accordance with superheat temperature. The fuel consists of stainless-steel clad U0 2  rods 21 in channels in a mass of Al 2 O 3  in tubes 26 of Zr; a stagnant steam space is left inside each tube 26.
